Creating a Video Wall Mosaic with DISPLAX Tile

When using multiple DISPLAX Tile units together, you can merge them into a single large display (mosaic) using your graphics card control panel.
This allows the operating system and applications to treat all Tiles as one unified screen.

Overview

A video wall mosaic combines multiple physical displays into a single logical display.
This configuration is handled entirely by the graphics card, not by DISPLAX Connect.

ℹ️ Note:
The example below uses an NVIDIA graphics card, but similar steps apply to other vendors that support videowall or mosaic features.

⚠️ Important Before You Start

Before configuring the mosaic:

  • Ensure all Tile units are set to Landscape orientation in:

    Windows Settings → Display

  • This must be done even if the final installation will be Portrait.

  • Orientation changes for portrait layouts are handled later inside the Mosaic setup.

Skipping this step may result in incorrect display mapping.

Step 5 – Arrange Tile Positions

  1. Arrange the Tile displays to match their physical layout

  2. Ensure alignment matches the real-world installation

  3. Click Next, then Apply

Apply

Step 6 – Confirm Changes

  1. When prompted, click Yes to keep the changes

The Tiles are now merged into one large display

Bezel Correction

After creating the mosaic:

  1. Proceed to Bezel Correction

  2. Typical bezel correction value is 24 pixels

    • This may vary slightly depending on the installation

  3. Click Apply, then Finish

Bezel correction ensures visual continuity across Tile borders.

Final Notes & Best Practices

  • Always perform mosaic setup before touch calibration

  • After mosaic creation:

    • Recalibrate touch using DISPLAX Connect

  • Test:

    • Full-screen applications

    • Touch accuracy across Tile borders

  • Ensure GPU drivers are up to date

⚠️ Common Mistakes to Avoid 

  • Setting portrait mode before mosaic creation

  • Mixing different refresh rates across Tiles

  • Skipping bezel correction

  • Calibrating touch before the mosaic is created
